AMD’s next-generation value and mainstream products are set to bring DirectX 10 and high-definition video playback to the masses. Although AMD is late to the DirectX 10 game, the upcoming RV610 and RV630 feature second-generation unified shaders with shader model 4.0 support. AMD has remained hush over the amount of unified shaders and shader clock speeds of its next-generation value and mainstream products though.

AMD is prepared to take on NVIDIA’s PureVideo HD with its next-generation AVIVO video processing. AVIVO is receiving its first upgrade since its introduction with the Radeon X1k-series with the RV610 and RV630. This time around, AMD is integrating its Universal Video Decoder, or UVD, for hardware decoding of H.264 and VC-1 high-definition video formats.

AMD’s UVD expands on the previous generation’s AVIVO implementation to include hardware bit stream processing and entropy decode functions. Hardware acceleration of frequency transform, pixel prediction and deblocking functions remain supported, as with the first generation AVIVO processing. AMD’s Advanced Video Processor, or AVP, has also made the cut for low power video processing.

Integrated HDMI with support for HDCP joins the next-generation AVIVO video processing for protected high-definition video playback. Unlike current HDMI implementations on PCIe graphics cards, RV610 and RV630 integrate audio functionality into the GPU. Instead of passing a PCM or Dolby Digital signal from onboard audio or a sound card, RV610 and RV630-based graphics cards can directly output audio – removing the need of a separate sound card.

RV610 and RV630 support PCIe 2.0 for increased bandwidth. Native support for CrossFire remains, as with current ATI Radeon X1650 XT and X1950 Pro products. AMD will also debut RV610 and RV630 on a 65nm manufacturing processor for low-power consumption. Expect RV610 products to consume around 25 to 35-watts. RV630 requires more power at around 75 to 128-watts.

AMD currently has four RV610 reference designs based on two RV610 variants – Antelope FH, Antelope LP, Falcon FH and Falcon LP reference boards and RV610LE and RV610PRO GPUs. Antelope FH and Antelope LP are similar; however, Antelope LP is the low-profile variant. Both reference boards feature 128MB or 256MB of DDR2 video memory clocked at 400 MHz. Antelope boards employ the RV610LE, feature passive cooling and consume less than 25-watts of power.

The Falcon FH reference board is the performance variant and designed for the RV610PRO ASIC with 256MB of GDDR3 video memory. AMD estimates board power consumption at approximately 35-watts, though it is unknown if Falcon FH boards will feature active or passive cooling. Falcon FH is the only RV610 reference board to support AMD’s CrossFire bridge connector for hardware CrossFire support. Falcon FH also features VIVO capabilities.

RV630 has three reference board configurations – Kohinoor, Orloff and Sefadu. Kohinoor is the high-performance RV630 variant and features 256MB or 512MB of GDDR4 memory. It also features VIVO and dual dual-link DVI outputs. However, it consumes the most power out of the three RV630 reference boards, requiring 121-watts for 256MB models and 128-watts for 512MB models.

Orloff falls in the middle with 256MB of GDDR3 video memory. Orloff lacks the video input features of Kohinoor but supports HDMI output. AMD estimates Orloff to consume less than 93-watts of power. Kohinoor and Orloff support PCIe 2.0 and native CrossFire. Kohinoor and Orloff require additional power via PCIe power connector though.

Sefadu falls at the bottom of the RV630 lineup and features 256MB or 512MB of DDR2 video memory. HDMI remains supported, as with Orloff though. Power consumption is estimated at less than 75-watts, and does not require the additional power supplied by a PCIe power connector. All RV630 boards feature 128-bit memory interfaces and occupy a single-slot.
